PROBLEM TO BE SOLVED: To decrease the production of the secondary product and to isolate a desired product from the reaction mixture at a low cost by using a solid electrolyte and an electrolytic liquid having a specified compsn. to carry out oxidation. SOLUTION: The solid electrolyte consists of a cation exchange membrane or lots of layers of the membranes. The electrolytic liquid is an org. soln. containing no supporting electrolyte and contains, by wt.%, 10 to 90% of methanol, 1 to 50% of a compd. selected from compds. expressed by formula I and formula II, 1 to 50% of 1-15C carboxamides which may be N-alkylated, and 0 to 30% of inert solvent. In the formulae I, II, R' independently represents hydrogen, 2-4C alkyl groups or the like, A independently represents methylene or the like, B independently represents H or O-CH3, m is 0 to 3, n is 1 to 3, X and Y are the same as A and B, respectively, but are selected in such a manner that the oxidation state of the compd. of formula II is lower by at least 1 than the oxidation state of the compd. of formula I.
